[architecture] Long-term agent memory returning outdated facts that contradict current reality

Implement memory decay via TTL \(Time-To-Live\) metadata and recency-weighted retrieval scoring, and use LLM-driven consolidation to update or invalidate stale memories.

Journey Context:
Vector databases retrieve based on semantic similarity, ignoring time. If a user moves from NYC to SF, querying 'where does the user live?' might return the older, heavily referenced NYC memory. Simple timestamp filtering is too rigid. The right pattern is hybrid scoring \(similarity \* recency\_weight\) and a memory curation step where the agent actively reviews and deletes/updates conflicting memories when new information is introduced.
